An in-situ thermoelectric measurement apparatus inside a thermal-evaporator
Kien Trung Nguyen, Giang Bui-Thanh, Hong Thi Pham +3
At the ultra-thin limit below 20 nm, a film's electrical conductivity, thermal conductivity, or thermoelectricity depends heavily on its thickness. In most studies, each sample is…
High-performance electronic cooling with superconducting tunnel junctions
H Courtois, Hung Q. Nguyen, Clemens Winkelmann +1
When biased at a voltage just below a superconductor's energy gap, a tunnel junction between this superconductor and a normal metal cools the latter. While the study of such device…
A cascade electronic refrigerator using superconducting tunnel junctions
H. Q. Nguyen, J. T. Peltonen, M. Meschke +1
Micro-refrigerators that operate in the sub-kelvin regime are a key device in quantum technology. A well-studied candidate, an electronic cooler using Normal metal - Insulator - Su…
InAs nanowire with epitaxial aluminium as a single-electron transistor with fixed tunnel barriers
M. Taupin, E. Mannila, P. Krogstrup +6
We report on fabrication of single-electron transistors using InAs nanowires with epitaxial aluminium with fixed tunnel barriers made of aluminium oxide. The devices exhibit a hard…
A robust platform cooled by superconducting electronic refrigerators
Hung Q. Nguyen, Matthias Meschke, Jukka P. Pekola
A biased tunnel junction between a superconductor and a normal metal can cool the latter electrode. Based on a recently developed cooler with high power and superior performance, w…
Sub-50 mK electronic cooling with large-area superconducting tunnel junctions
H. Q. Nguyen, M. Meschke, H. Courtois +1
In electronic cooling with superconducting tunnel junctions, the cooling power is counterbalanced by the interaction with phonons and by the heat flow from the overheated leads. We…
Trapping hot quasi-particles in a high-power superconducting electronic cooler
H. Q. Nguyen, T. Aref, V. J. Kauppila +4
The performance of hybrid superconducting electronic coolers is usually limited by the accumulation of hot quasi-particles in the superconducting leads. This issue is all the more…
